Wiperless windshields in your future? Thanks, nanotech.

It's really too bad nanotechnology is so gosh darn morally unacceptable, it could do so much good for humanity! Take this new wiperless windshield, for instance. Designed by Leonardo Fioravanti of Pininfarina, the Hidra features an aerodynamic design, and a bit of a nanotech sandwich (mmm, sandwich) to keep the front glass clear of water and debris. The first layer protects from sun and repels water, the second layer features "nano-dust" to push dirt to the edges of the windshield and is activated by the third layer which senses the dirt, while the whole kit is powered by the fourth layer which conducts electricity to keep it going. The tech could be ready for mass production within 5 years, but there's already a working prototype in the Hidra concept car.
